What is the matrix for?
How can I use the matrix?
The different stages of a project are listed along the side of the matrix:
For each box within the matrix a series of questions or prompts are included that will help you to consider sustainability issues, assist with the decision making process and to keep a record of developments of your project overtime.
By clicking on:
The boxes that the questions that are shown relate to are highlighted in blue.
On clicking on an individual question you are presented with two data entry boxes.
Click on the update question to register the response.
When a response has been entered into the answer box the red light next to the question in the list will turn green. As questions for a box in the matrix are completed the box will be shaded a darker green to illustrate that this stage and aspect has been considered. This will enable you to identify stages or aspects that may be neglected.
Please note - Not all questions will be applicable to every project due to the project type, size or the stage of the project. Therefore it is expected that the completed PETUS matrix will usually be composed of white, light green and dark green boxes
